i don't have any problem anymore after switching from 3.4 to the trunk
version
it seems it has fixed the issue.

This is great to hear.  If you do find another issue with block
frequency, please CC me on the bug report.

The testcase might be interesting to look at regardless, if you're
willing to mail it.  I don't have any clear examples of slowdowns in the
old algorithm, and I'd be interested to have a closer look at what's
going on with this one.

i entered bug #20410
finally :
3.4
==switch inst :      llc compilation time OK,  execution time OK
indirect branch :  llc compilation time KO

trunk
===switch inst :      llc compilation time OK,  execution time KO
indirect branch :  llc compilation time OK,  execution time OK
